When zinc reacts with sulphuric acid the salt formed is
-
Zinc sulphate
-
Zinc oxide
-
Zinc nitrate
-
Zinc chloride
Correct Answer
A. Zinc sulphateExplanation
When zinc reacts with sulphuric acid, the salt formed is zinc sulphate. This is because zinc displaces hydrogen from sulphuric acid, resulting in the formation of zinc sulphate and the release of hydrogen gas.Rate this question:

Magnesium hydroxide reacting with hydrochloric acid is called
-
Neutralisation reaction
-
Oxidation
-
Reduction
-
Displacement
Correct Answer
A. Neutralisation reactionExplanation
When magnesium hydroxide reacts with hydrochloric acid, it forms magnesium chloride and water. This type of reaction is known as a neutralization reaction because an acid and a base react to form a neutral product, which is water in this case. The hydroxide ions from the magnesium hydroxide combine with the hydrogen ions from the hydrochloric acid to form water, while the remaining ions combine to form magnesium chloride. This reaction results in the neutralization of the acidic and basic properties, hence the term "neutralization reaction".Rate this question:

When metals react with acid we get
-
Salt and water
-
Salt and oxygen
-
Salt and hydrogen
-
Salt and nitrogen
Correct Answer
A. Salt and hydrogenExplanation
When metals react with acid, they undergo a displacement reaction where the metal displaces hydrogen from the acid. This results in the formation of a salt and hydrogen gas. Therefore, the correct answer is "salt and hydrogen".Rate this question:

Copper will not react with acid because
-
Copper is less reactive than hydrogen
-
Copper is more reactive than hydrogen
-
Copper is more reactive than chlorine
-
None of these
Correct Answer
A. Copper is less reactive than hydrogenExplanation
Copper will not react with acid because it is less reactive than hydrogen. This means that copper does not readily give away its electrons to form positive ions, unlike hydrogen. As a result, copper does not easily react with acid to produce a reaction.Rate this question:
